Why do storms often follow the West-North direction?

Storms often follow the North-West direction because they are affected by many direct and indirect conditions.

Storms are forecasted in 16 main directions

According to the National Center for Hydrometeorology, the storm is a giant column of air moving in the center in an anticlockwise direction (in the northern hemisphere), the movement of the storm is the movement of the whole column. That gas. As a vortex movement moves forward of the storm, in fact the path of the storm is very zigzag. Predicting the direction of movement of the storm is the same as forecasting the movement speed is defined as the average travel direction (main direction) of the storm within 12 hours or 24 hours.

Why do storms often go west - northwest?

There are many directions of storms that can move in the process of formation and development. However, many storms tend to move in the north-west direction because the storm is affected by many direct and indirect causes.

A super typhoon is at a strong development stage.

There are two types of forces that cause storms to move, namely internal forces and external forces . Internal force is the force generated in the storm itself. Because the storm itself is a whirlpool of air against the direction of the clock, the direction of movement of each point in the air has been influenced by the phenomenon of Earth turning around and generating a deviation direction.

The effect of this deflection in the northern hemisphere, making the points in the air flow tend to shift to the right, moreover, the latitude is getting higher and higher, the effect of the deflection is increasing. This makes the wind from the north to the west, which has many points in the air, has shifted a number to the north; Windstorms from the south blowing to the east, which had little point in the air, moved a quantity to the south.

Thus, the quality of air in the south of the greater storm in the north, storms with net weight shift north. This net weight can be attributed to the main internal force in the path of the storm. Next, the air in the storm area is the air that flies up high. The elevated air under the action of Coriorite force (moving in the direction of the Earth's deviation), tends to move to the West, which can also be attributed to the internal force of the storm. The combined effect of these two internal forces causes storms to tend to move north to the West.

Typhoon landfall often causes great consequences.

Foreign forces are the driving force behind the storm when air flows around a typhoon on a large scale. In the summer and autumn, the Pacific Ocean often has an independent high-pressure air flow (often referred to as the tropical sub-high pressure), the wind direction at these four elevations has a relationship with the child. The path of the storm. The storm was born in the southern vicinity of the Pacific high pressure, where the East wind blew, the storm prevailed to the West.

Internal forces and external forces combine to make the direction of the storm often follow a certain rule. But during its movement, it was greatly influenced by tropical sub-pressure in the Pacific Ocean . During the early period, the storm in the southern side of the tropical sub-high pressure, it often moved in the northwest direction, once reaching the western edge of the tropical sub-high pressure range, it would proceed to the northwest of the center. The sub-tropical high pressure, now, the external force it gains will change, prompting it to turn east, in conjunction with internal forces, causing the direction of the storm to turn northwest.

Due to the intensity of the sub-tropical high pressure, stretching to the west and narrowing in the east, along with different intermittent conditions, the route of the storm was not the same. If the sub-tropical high pressure strip is extended in the West and strengthened, the storm's path also deviates to the south, straight to the West; If the tropical sub-high pressure strip in the north of the storm recedes to the east or breaks, the storm may move to the north where there is a fault or to the west of the high pressure area, then move to the northeast. . In short, the path of the storm is formed by the Parabola.

Picture a storm taken from a satellite.

Understandably, in the oceans in the summer, there is a lot of water accumulation due to the sun's heat wave. At the end of the summer, the air is colder, so the steam turns into rain, tropical depression and storms. In fact, they appear in the middle of the ocean and drag on the opposite west coast of the Earth.

However, at present, people still do not fully understand the rules of the movement of storms. Therefore, the forecast of the direction of the storm is not true.
